Hi
I have a computere with windows 7 x64 there, no matter what i do, won't run mathcad 15.
The installation seems to be completed without any problems, but when i try to run the application, the splash screen shows up, but after a short period of time, the application crash without any error messages except the Windows own "Mathcad application has stopped working". I have another computer also with windows 7 x64, and here the application will start without any problems 
. The only differense between these computers is that the first one is a "samsung" installation width showelware and all, and computer nr. 2 is a vanilla installation of windows.
I have tried the following
Reinstallation of MSXML 4.0 SP.2
---------||--------- of .Net, i can't remember the version, but it was the newest I could find.
Reinstallation of the computer (with the samsung disk)
But nothing seems to work. Mathcad 14 worked without any problems...
I hope somebody will help, and sorry for my bad english, i´m a dane
